Common Name

Blaxell’s Wattle




Largely confined to an area between Frank Hann Natl Park (c. 160 km SW of Norseman) N to McDermid Rock (c. 100 km W of Norseman), except for one collection from near Hyden, c. 150 km W and one from near Norseman, c. 90 km due E, W.A.


Spreading ±dense shrub 0.3–1.2 m high. Branchlets tomentulose to densely puberulous (hairs patent to ±appressed). Phyllodes on raised stem-projections, ascending to erect, narrowly oblong to oblong-elliptic, straight, 1–2 (-2.5) cm long, 3–5 mm wide, l:w = (3-) 4–6, obtuse, inconspicuously mucronulate, ±thick and fleshy, glabrous except pulvinus densely puberulous to tomentulose; midrib not prominent; lateral nerves absent or obscure; gland basal, obscure. Inflorescences rudimentary 2-headed racemes with axes < 0.5 mm long; peduncles 7–22 mm long, glabrous; heads globular, 3.5–4.5 mm diam., 17–31-flowered, golden. Flowers 5-merous; sepals free, sometimes absent. Pods variably undulate to circinnate or irregularly sigmoid, to 2 cm long, 3.5–4 mm wide, thinly coriaceous, glabrous. Seeds longitudinal to oblique, broadly elliptic, c. 2 mm long, glossy, black; hilum sublateral; aril linear-clavate, 2/3–3/4 length of seed, white.


Grows in red-brown clay in flatland or in loam on low rocky hill-country, in shrub mallee or eucalypt woodland.


W.A.: between Bremer Ra. and the Lake King–Kumarl road, B.R.Maslin 5431 (G, MO, PERTH); 25 km ESE of Tadpole Lake, Frank Hann Natl Park, K.Newbey 5537 (AD, NY, PERTH); 4.8 km E of Graham Rock turn-off on the Hyden–Newdegate road, M.H.Simmons 1327 (PERTH).


Similar to A. evenulosa which has minutely hairy branchlets, generally larger phyllodes with the gland 1–4 mm above the base; and A. saxatilis which has glabrous branchlets, generally larger phyllodes with the gland 1–2 mm above the base.
